BICSI - INSTALLER 1 COURSE QUESTIONS WITH 100% ACCURATE ANSWERS





25-pair color code - (ANSWER)White - Blue, orange, green, brown, slate

Red - Blue, orange, green, brown, slate

Black - Blue, orange, green, brown, slate

Yellow - Blue, orange, green, brown, slate

Violet - Blue, orange, green, brown, slate



Fiber color code - (ANSWER)Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet, Rose,
Aqua



NVP - (ANSWER)Nominal Velocity of Propagation



Insertion loss - (ANSWER)The difference in the amount of power received before and after something is
inserted into the circuit.



Resistance - (ANSWER)Resistance is expressed in Ohms, and is the property of a conductor to resist the
flow of electricity through it. V=IR



Inductance - (ANSWER)Is a property of an electromagnetic field built around a conductor that opposes
any change in the current flow in a circuit



Capacitance - (ANSWER)is a property of conductors that allows storage of electric charges when
potential differences exist between the conductors.



Impedance (V) - (ANSWER)Total opposition of current flow measured in Ohms



American Wire Gauge (AWG) - (ANSWER)A standard rating that indicates the diameter of a wire, such as
the conducting core of a coaxial cable or the twisted pairs in a UTP cable.



Megahertz (MHz) - (ANSWER)one million hertz, especially as a measure of the frequency of
transmissions






Megabit (Mb) - (ANSWER)Approximately one million bits. Often used as a measurement of data transfer
throughput.



Bandwidth - (ANSWER)The amount of data that can be transmitted over a network in a given amount of
time.



Decibel (dB) - (ANSWER)A unit used to compare the loudness of different sounds.



Crosstalk - (ANSWER)when data bleeds from one pair to another in a cable



Alien Crosstalk (AXT) - (ANSWER)Unwanted signal coupling from one permanent link to another



USOC - (ANSWER)Universal Service Order Code



Coaxial cable types - (ANSWER)Series-6 and Series-11



Coaxial connectors - (ANSWER)Series-6 uses BNC and F connectors

Series-11 uses F and N connectors



Fiber connectors - (ANSWER)SC, ST, and SST(LC or



cladding - (ANSWER)The glass or plastic shield around the core of a fiber-optic cable. Cladding reflects
light back to the core in patterns that vary depending on the transmission mode. This reflection allows
fiber to bend around corners without impairing the light-based signal.



Multimode Fiber (MMF) - (ANSWER)Larger core with multiple paths of light. Common for backbone and
horizontal cabling in buildings. OM2 - Not recommended for new installs. OM3 - Higher bandwidth. OM4
- Highest bandwidth for MMF. 2000m/6500ft limitation. 850 nm and 1300 nm (nanometers)

Ribbon Fiber - (ANSWER)Multiple 250 um fibers bonded into a flat color coded ribbon. Can splice a
bunch at a time.
